Microstructural response and strain hardening in deep cold rolled nickel-based superalloy for aerospace application
Fatigue crack resistance is a critical factor for the performance of aero-engine components. Deep cold rolling (DCR) is one promising surface enhancement technique, as it generates deep compressive residual stresses with ...
Design of Alporas aluminum alloy foam cored hybrid sandwich plates using Kriging optimization
Sandwich structures are shown to have better blast resistance when compared to the solid metallic plate for the same weight. Hybrid Sandwich Panel (HSP) further increases the blast resistance with addition of hyper-elastic ...
A numerical and experimental study of distribution of the residual stress on the shot peened low alloy steel
Shot peening is a cold working process, which is used to enhance the properties of materials, especially the fatigue life as it induces large compressive residual stresses in the subsurface of materials. In this paper, the ...
